From mboxrd@z Thu Jan 1 00:00:00 1970 From: Michal Simek Date: Thu, 22 Oct 2020 12:32:13 +0200 Subject: [PATCH 01/10] arm64: zynqmp: Fix zynqmp mini qspi max frequency In-Reply-To: References: Message-ID: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de From: T Karthik Reddy For zynqmp qspi, frequencies up to 40MHz will work irrespective of feedback clock enabled or disabled. If we want higher than 40Mhz the feedback clock should be enabled. With spi-max-frequency 108MHz it is not working when the feedback clock is disabled. Change it to 40MHz so that it works irrespective of feedback clock enabled or disabled.
